The YouTube video embedded above shows all GOES-13 (GOES-East) Full Disk Water Vapor (6.5 µm) images for all of September 2015. The 10.7 µm Infrared window channel animation is shown below. Animations for GOES-15 (GOES-West) are at the bottom.

GOES-13 animations show more tropical activity over the Atlantic, as expected from climatology, during September compared to August.

The GOES-15 animations show many tropical cyclones in both the eastern and central Pacific Ocean. Indeed, 2015 ranks as the most active year for the central Pacific for Tropical Cyclones (Hurricane Oho, now south of Hawaii, is the 12th named storm of the year).
